The document summarizes the water cycle through the processes of evaporation, condensation, precipitation, run-off, and replenishing groundwater supplies. Evaporation occurs as the sun warms water, turning it into vapor released by plants, trees, and grass. Condensation happens when water vapor cools and changes back to liquid, forming clouds. Precipitation results when so much water has condensed that it falls as rain, snow, or hail. Run-off describes water flowing downhill into rivers, lakes, and other bodies of water. This run-off also replenishes groundwater supplies.
